' .i Specification of Letters Patent.

Patented March 13,v y190e.

Application iled July 3, 1905. Serial No. 268,142.

To @ZZ whom it may concern: Be it known that I, EMIL HERTENSTEIN, a citizen of thel United States, residing at Meriden, in the county of New Haven and State of Connecticut, 'have invented a new and useful Improvement in Permutatio'n-Locks g and I do hereby declare the'following, when taken in connection with the accompanying y'drawings and the numerals of reference marked thereon, to be a full, clear, and exact description ofthe same, and which saiddrawings part of this specification, and represent, in e v Figure 1,Y a broken plan view of ahand-bag provided with a permutation number-lock constructedin accordance with. my invention Fig. 2, a detached view, in side elevation, of the lock `as removed from the bag Fig. 3, a reverse plan view thereof; Fig. 4, a view thereof in vertical longitudinal section, showing the locking-plate in its drawn or open position; Fig. 5,-.a reverse plan view of the lock with f the locking-plate removed; Fig. 6,.'a plan view of the locking-plate ,'Fig.

7, a view thereof in side elevation; Fig'. 8, a broken plan view showing the keeper applied to the pivotal inner frame of the bag.

Myinvention relates to an improvement in permutation-locks 'of the class known as number-locks,. the object being to Vproduce cation to hand-bags.L

With these ends in view my invention con-Y sists in a permutation-lock having certain details of construction, as will be .hereinafter` described, and pointedout in the claims.

In carrying -out my invention as herein shown I employ a long narrow-chambered lock-case -2, slightly narrower in width-than the pivotal outer frame 3 of the bag and formed at its ends with screw-holes4 for the reception of screws, by means of which itis secured to the said frame 3. Midway of its4 length it is formed with a long boss 6,' forming a chamber v7, in which the lockingmechanism proper is housed. On the top of this boss 6 I locate two ro'tary'knobsS and 9 and a finger-button 10,`fthe`knobs 8 and 9 and their adjuncts vcorresponding each to the other. The knob 8 terminates at its lower end in a hollow hub 11, located within the left-hand end of the chamber 7 and containing a lateral slot 12, coacting with a locking- I 'lug 13, projecting upward into the hub 11l` from .theleft-hand end of a sliding lockingplate .14, occupying'the lower portion of the Vchamber 7 and parallel with the top of the boss 6. The lower end of the knob 9 terminates in a corresponding hollow hub 15, hav- 17, suitably located upon they said plate 14. Alu 18, located between the lugs 13 and 17 and ormed upon the outer edge of the plate 14, coacts with a horizontally-arran ed inwardly-projecting keeper-hook 19, ocated atthe left-hand end of a'keeper 20, secured 6o I ling a lateral slot 16,receiving a locking-lug V to the inner pivotal frame 21 of the bag, the two frames 3 and 21 being made in the usual form and pivoted together and constituting,

as it were, the two jaws of the mouth of the bag. At the right-hand end of the keeper 20 is a corresponding keeper-hook 22, which coacts with a web23, vformed by undercutting a block 24, located upon the upperface of the extreme right-hand end of the lockingplate 14. Openings 6iL in the inner wall of the boss 6 are provided to admit the keeperhooks 19 and 22 into the chamber 7 within the boss 6. The said block 24 carries a threaded .post 25which projects upwardly through a hub-like sleeve 26, mounted in the .right-handend of the top of the boss 6, which isformed with a slot 27 `for the reception of-V the sleeve 26, which is free to rotatein the said slot as well as to be moved longitudinlally therein and which is formed with a slot 28, corresponding to the slots 12 and 16 of the hubs 11 and 15 and coacting with a fixed locking-finger 29, locatedin the center ofthe extreme right-hand end of the chamber 7.

The button 10 is mounted upon this part and provides for the sliding ofthe plate 14 in opening the lock. A spiral spring 30, interposed between theblock 24 and the righthand end wall of the boss 6, exerts la constant effort to move the plate 1.4 from right to left, and hence into its locked position. In thelocked positionof the plate 14 the lug 13 Yis located'within the slotted hub 1l, the

lug 17 within the slotted hub 15, and the slot- Y tedsleeve 26 at the left-hand end ofthe slot IOO 27. vThehubs 11 `and 15 are ynow freeto be turned in eitherdirection by their knobs -8 f and 9, whilethe sleeve 26 is free to be turned in either direction by check-nuts 33 and 36 applied to its upper end.. Althoughthe knobs 8 and are free to be turned in either direction and independently of each other, when the lock is locked it is apparent that the lock can be unlocked only when the slots 12 16, and 28 are brought into line to permit the locking-plate 14 to be drawn from left to right, whereby the lug 13 is moved into the slot 12, the lug 17 into the slot 16, and the lug 29 into the slot 28. For the alinement of the slots 12, 16, and 18 the knobs 8 and 9 and the sleeve 26 are turned in accordance with a predetermined combination of numbers placed upon the upper faces of checknuts 31, 32, and 33, respectively mounted upon the knobs 8 and 9 and upon the sleeve 26, the said knobs andsleeve being threaded for thefpurpose. These check-nuts coact with corresponding lower check-nuts 34, 35, and36, also respectively mounted upon the threaded portions of the knobs 8 and 9 and the sleeve 26. Washers 37, located below the lower check-nuts 34, 35, and 36, rest upon the top of the boss 6. 1

To set the lock, three numbers are chosensay H3 2 2 7-and the check-nuts shifted and tightened, so that when the slots 12, 16, and 28 are in line the numbers 3 2 2 upon the upper check-nuts 31, 32, and 33 Will be in line and'- facing from left to right. Now when it is desired. to open the lock the knobs 8 and 9 and the sleeve 26 are turned in one direction or the other to bring the numbers 3 2 2 into line. This done, the button 10 is seized for drawing the locking-plate 14 from left to right, whereby the keeper-hooks 19 and 22 are freed from engagement by the lug 18 and Vweb 23 of the plate 14. The bag may now be opened; but the. knobs 8 and 9 andthe sleeve 26 cannot be turned until the plate 14 has been moved from right to left, so as to again unlock and freethe hubs 11 and 15 andthe sleeve 26. As shown7 the ends of the lock-case 2 are formed with transverse grooves 38for thereception of the rings (not shown) used for the attachment of the handle ofthe bag.

By making the hubs 11 and 15 hollow for 'the reception of the-lugs 13 and 17, respectively', I secure an economy ofV space not otherwise attainable and extremely important in the'construction of small locks for small bags.

It is apparent that i'n carrying out my invention some changes from the construction hereinshown and describedmay be made. Thus the number of knobs maybe varied, and letters or other characters might replace numbers upon the upper check-nuts, so that instead of founding the combination upon a number it might be founded upon a name or a word or upon the initials of the person own- Y ters Patent, is-

1. In a permutation-lock, the combination with a lock-case, of one or more hollow slot- 7 o ted hubs mounted therein, and a sliding locking-plate having locking-lugs normally conlined within the said hollow slotted hubs which are rotated to bring their slots into registration with the said lugs.

2. In a permutation-lock, the combination with a lock-case, of one or more slotted hubs mounted therein, a locking-plate having one or more lugs normally located within the said hubs which are rotated for bringing their slots into registration with the said lugs, and upper and. lower check-nuts adjustable with respect to the said hubs for resetting the look, the upper check-nut being provided with characters to guide the rotation of the hubs,

3. In a permutation-lock, the combination with the case thereof, of one or more slotted hubs mounted therein, a slotted rotary and longitudinally movable sleeve mounted in the said case, a sliding locking-plate having lugs coacting with the said slotted hubs and with a stem or post passing through the said sliding sleeve, and upper and lower checknuts combined with the said hubs and with the said sleeve.

4. In a permutation-lock, the combination with a lock-case having a chambered boss, of one or more rotary knobs mounted therein and terminating at their lower ends in slottedv hubs, upper and lower check-nuts ad justably roo mounted upon the said knobs, a rotary and longitudinally -movable sleeve mounted in the said boss and formed with a slot, a sliding locking-plate located within the said boss and carrying lugs coacting with the said slotted 105 hubs, a post carried .by the said plate and rising through the said sleeve, a finger-button applied to the upper end of the said post, a sp ring tending to move the plate into its locking position, the said plate also carrying means for 11o engagement by a keeper, and check-nuts applied to the said knobs and sleeve for setting the lock.

In testimony whereof I have signed this specification in the presence of two subscrib- 1.15
